Simple Problem, I think theres not enough information

In Figure 8-50 (nothing important other than 1.2 m height difference, the higher level is completey flat), a block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed v0 is 6.0 m/s, the height difference h is 1.2 m, and the µk is 0.60. Find d.

Vo = 6.0 m/s
h = 1.2 m
µk = 0.60
m = ??? (not given)

2. Relevant equations

Conservation of energy to get initial velocity upon reaching the higher level (this is already done and verified)

Then for the friction force we need the normal force (in this case weight of block), which is not given...

3. The attempt at a solution

So I already have the initial velocity at the higher level done and verified that part is correct, but I don't think the distance d it takes to come to a stop can be found since they never gave the weight of the block (so unknown magnitude of friction force).
